Yes because a 223 cant reap half as much havoc a 243 can!
For me this goes all the way back to the handgun ban. Loads of hand gunners suddenly wanted to go stalking so deer calibre were handed out like toffees licence wise.
Most of them tried it and found out it involved sweating alot or freezing your hands off so gave up. Plod soon realized they had granted licenses with what amounted to not very much of a good reason!
Plod doesn't do egg on his face, others have to pay for it!
